"I use this lens on the D3s and it is absolutely amazing with this camera for sports. There are many other uses besides sports, but all I can say is the sharpness, fast focus and image quality is the best I have ever seen independent of cost. There are many other more technical reviews out there so I wanted to tell you from a real-world perspective that this lens will produce top-notch professional results for any level (pro, college, high school, etc) day after day." bhphotovideo.com
